I've re-purposed old hacksaw blades for other uses too. Noticed that the back of the blade is sometimes different acting material than the front (toothed side):
"Bimetal blades are made with a high-speed steel cutting edge that is welded to a spring steel blade back."
Some blades (carbon?) seem to be softer, less springy on the back side. May just have been the particular blade I was using, but you may want to keep this in mind if you get unexpected results...
I've not been able to find the silicon-carbide cutoff wheels you mentioned. Only grinding stones.
Perhaps an angle grinder is better for this?
Thanks.

[reply]Hmm. I think they have them at the local Home Depot, here in Edison. Do you ever cross the bridge to shop over here? A lot of Staten Islanders seem to. (The toll on the Outerbridge Crossing is now a killer, however.)
I'll check at HD tomorrow and see if they still have them. They' a little over 1" in diameter, if my memory is correct. You get a whole stack of them in a little plastic tube.

[reply]Personally, I wouldn't use one for that job, but maybe someone else knows about using thin cutoff wheels in an angle-head grinder.

I do that all the time. It works great! Use lots of ventilation though. The grit flying off the wheel is nasty stuff.

I just break the blade. Clamp the section you want to use in the vise horizontally, hold a steel block against the vise jaw and protruding part at a small angle and hit the block with a hammer. The block concentrates the force at the edge of the jaws and more or less shears off the blade.

The EZ-Lock looks pretty slick. How do they perform compared to the regular cheapies?
(...)
They perform about as well as the plain-arbor discs.
One caveat for those of us that are um. economically oriented is that one cannot use the EZ Lock discs down to the same tiny diameter to which one can use the less expensive plain-arbor style.
Rumor has it that if you should happen to (cough) drop the nose of the tool on to the floor, the dented EZ Lock can be time-consuming to remove.

Ok, I assume that these are what you are referring to for use in a Dremel:

Yup. Those are the ones. You need a mandrel, if you don't already have one.

BTW, I checked HD for those wheels and they're $10 for a pack of 20. So your online deals will be better if the shipping doesn't eat up the difference.
Will this work?
I think I have one of those plastic cutting tools somewhere. But I hated using it on plexiglass because it was difficult getting it to stay against the straight edge when cutting.
I was at Home Depot today, and couldn't figure out what kind of blade you were referring to for a Stanley utility knife.
I saw drywall, roofing, hook, carton, snap-off, and utility blades. What exactly should I be looking for?
Thanks.

Ok. I'll just try the "Heavy Duty" blades I saw.
